CA 2072204

A recording/reproducing method and device for an automatic performing piano which not only seizes performance information according to occurrence and timing of an on- event, but also converts the performance information according to actual emission timing in each respective recording and reproducing process steps, thereby achieving accurate performance reproduction with balance and high fidelity. Since a time lag between depression of key and emission of sound varies with the intensity in depressing of the keys, this time lag is incorporated into performance information to be stored, a key drive solenoid can be actuated or terminated in immediate response to the output of key depression or release data, respectively.
